| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using an incorrect size wrench, leading to cam-out and fastener damage. | Always use a wrench or socket that precisely fits the 34mm hex head to ensure proper engagement and prevent stripping. |
| Cross-threading the screw, which can damage both the screw and the mating component's threads. | Carefully start the screw by hand to feel the threads engage smoothly before applying any significant force. |
